a slow cooker Dawn
Gotta' love Moms! :D :D (Except of course, my Mama never did know how to do a roast)!
Crockpots are right up there with the microwaves. Best inventions.
Pressure cookers are pretty handy dandy too. :D Now Mama could do a mean pot roast in the pressure cooker. :D
They are indecently easy to use. Why would you think it was going to blow up? If there are no issues with the seal or valve it's fine. If there are issues, then it shouldn't be used.
My mum had one and she was stewing rhubarb and the valve blew. Every single surface in the kitchen was covered in rhubarb.
They kinda freak me out too. For me, it's the what if factor.
